SPECIFICATION forming part ofV Letters Patent No. 261,401, dated July 18, 1882. Application filed March 7, 1882. (No model.)

To all whom` it may concern Be it known that I, ALFRED W. SPERRY, a citizen oi' the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have' invented certain Improvements in Attaching Knife-Handles, of which the following is a specification.

My invention has for its object to connect the blades and the handles of knives and other articles of cutlery, and Vthis object I ell'ect through the medium of a cast-metal bolster in the peculiar manner hereinafter set forth.

In the drawings, Figure l is an external perspective view, showin g a knife, handle, and bolster illustrating my improvements. Fig. 2 is a longitudinal section of Fig. l. Fig. 3 is a perspective View of the handle. part longitudinal section of the handle in perspective. Fig. 5 is a side view ot' the end ot' the handle. Fig. 6 is a perspective view, showing the blade and bolster thereon detached from the handle. Fig. 7 is a view of the end the blade, and Fig. Sis an view ofthe hau The blade A of the knife, fork, or other ar.- tible is provided with a ta-ng widest at its outer end, and having a slot or notch to receive a portion of the handle. Thus the tang B, Fig. 7, has diverging edges a: :c and a ceutral slot, y, which slot receives a transverse portion, a, of the handle, Figs. 2, 3, and 4., thereby giving the blade a positive bearing upon the handle and preventing it from breaking loose, as results when the tang is sustained Wholly by the bolster. The handle has slots e to receive the forks cof the tang, which slots are widened to form-recesses f, Wider than the tangs, (see Fig.8;) and transversely across the handle is bored an opening, g, to the bottom of which the forks c o extend, as shown in dotted lines, Figs. 4 and 5. The sides of the handle near the end are cut away so as to leave dovetailed projections h. The width ot' the tang is somewhat less than that ot' the handle, as shown in dotted lines, Fig. 4, and the slot y is of such depth as to extend beyond the end of the handle when the shank bears against the bottom ofthe recess g, as shown in Fig. 4:.

Fig. 4 is a Y The bolster D is cast upon the blade and handle when the parts areV in the position shown in Figs. 2 and et, the metal filling the place in the mold beyond the ends of the handle, as shown in Fig. 5, dotted lines, and around the dovetailed projections h, the slot ybeyond the handle, the opening g, and the wider portions f of the side slots, thus covering and embedding the tang, which, owing to its greater width at the end, cannot be withdrawn from the bolster. Neither can the bolster be Withdrawn from' the handle, because, rst, of the transverse portion g', which extends beneath the bearing a of the handle, and, second, of the inwardly-projectin g portions h iittin g the dovetailed portions h ot' the handle.

It will be seen that the transverse portion g', side. strips, f', which tit the recess f, and cap portion m form an open frame, surrounding the cross-bearing a ofthe handle, and thus immovably secure the bolster and the handle, and that the spreading tang, being embedded in this frame, cannot be withdrawn without the fracture of some of the parts.

It will also be seen that as the tang has its lateral bearing upon the cross portion a the blade and its tang are prevented from rocking so as to Work the tang loose in the bolster.`

t will further be seen that the cross bearing portion a connects the cheeks or sides of the handle, so that the latter has not that tendency to spread as have those slotted completely across, and the lips h further tend to bind the ibers ot' the handle together and prevent spreading. The extension of theslot y beyond the handle insures the connection of the sides of the bolster beyond the handle by means ot' the cross portion yf, Fig. 2, thus preventing the sides of the bolster from being spread by the working of the knife-blade.

In consequence of the connection formed as above described, I am enabled to use much shorter tangs than would otherwise/ be possible, redueing to a considerable extent the cost of thein'iplement.

I do not limit myself to the precise construction shown, as the same may be varied. For instance, the dovetailed lips h may be dispensed with, the tang may be notehed at the pieces g mand side pieces, f f', forminga rectedges instead of being dovetailed, andthe slot angular frame, nclosing a solid portion of y and bearing a may be differently formed. the handle at the end thereof adjacent to the I am aware that east-metnlfrnmes have been blade, substantially as set forth. 1 5 5 extended completely around the handles, the In testimony whereof Iheve signed my name tangs being embedded therein, and I do notto this specification in the presence of two subclaim a tang embedded in d frame. scribing witnesses.
